Why the Jenny?

[CRISIS]

Aside from a more natural, full run being achieved on the jenny, the fact is (running a mill) a dog is "moving a belt" ... but on the ground a dog (running a jenny) is propelling himself forward ... which is a major difference.

Anyone who's ever run a treadmill in a gym "moving a belt" will tell you it's a joke compared to actually running cross-country outside ...

very true, once the momentum is going all your really doing is "lifting your legs" as compared to running you have no choice but to push your own weight!

which is one reason why i never really understood how the emill benefits a dog........i understand it still raises the heart rate which is the point behind cardio.....but the slatmill seems much more efficiant than the emill would ever be......


anybody have any good plans for a jenny???
